Jena Irene showed her rocker fangs with "Barracuda" to open the show, a "killer performance" that "set the bar high for everyone," according to Keith Urban, while Lopez said she had "a real chance" to make the finale.

Irene's country take on Underwood's "So Small" didn't disappoint either, as she gave Lopez "goosies" and prompted Urban to remark, "You're everything that Idol has always been about."

Woolf's country take on "You're Still the One" had the judges commenting more on how cute he was (Lopez) and how crazy he drove the girls (Urban) than his voice.

Jessica Meuse was "Slick" singing "Somebody to Love," which earned strong praise for her "fantastic voice," though the judges urged her to have more freedom.

Connick called Meuse's "Jolene" "strong and convincing," Lopez said her voice was "magnificent," and Urban loved her vocal but hated the "dark" arrangement.

C.J. Harris tried rocking "American Woman," and earned nice remarks, although Connick continued to question his intonation, Lopez said it was "shaky in the beginning," and Urban said he needed more attitude (though Urban misinterpreted the lyrics' true meaning).

His country song, "Whatever It Is," didn't go over much better, with Connick saying simply, "It wasn't your best performance" and hinting he needed luck to stick around.
